WINDOW ATTACHMENT.

Application filed October 3, 19-22. Serial NO. 592,169.

To (ZZZ who/ii it may concern:

Be it known that we, ROBERT E. Gnovns and ORA B. GARNAI-IAN, citizens ofthe United States, residing at Clarksburg, in the county of Harrison andState of est Virginiay'have invented a certain new and usefulIn'iprovement in Window Attachments, of which the following is a full,clear, and exact description.

The object of this invention is to provide a portable window attachmentin the form oi a cabinet or box. for use in containing foods, and whichmay be arranged in a window so as to project either out-side of thebuilding or inside of the room, and which may be converted into astudents natural light study or drawing table, or a window cleaningplatform, or painters stand, or a flower or plant table or stand, or aglass equipped hot-house for starting and maturing early plants, thedevice being capable of being placed securely in position in a windowwithout the use of screws or nails and without interfering with theopening and closing ot' the window.

The invention consists of a portable stand having a bottom provided withsliding cleats adapted to engage a window frame and to be clampedtherein in such engagement so as to be secure against accidentaldisplacement, and a detachable cover, as we will proceed now to explainand finally claim.

In the accompanying drawings illustrating the invention, in the several.views of which like parts are similarly designated, Figure 1 is avertical section illustrating the device projecting outside of thebuilding. Fig. 2 is a similar view showing the device arranged inside ofa room and without thecover. Fig. 3 is a perspective view or the standdetached. Fig. i is a vertical section through the connecting means.Fig. 5 is an inside elevation of the connecting means taken on line S-So t 4. Fig. 6 is a horizontal section taken substantially in the line6+6, Fig. 1. Fig. 7 is a perspective view 'of the closed cover. Fig. 8is a per spective'vie'w of theglaz ed cover. Fig. 9 is a perspectiveview of shelf. 10 is a partial cross section and sectional elevation ontheline 10 10 of Fig. 1.

The bottom or platform 1 is made of suitable material and of properdepth for the purposes of the device and of the width to fit within thewindow opening. On opposite.

sides of this bottom are erected posts 2 preterably braced by angleirons or brackets 23 which are secured to the bottom and the posts byscrews or bolts 4. The fronts of these posts are provided with thetransverse grooves 5, and they are pierced from front to rear with holes6, shown more especially in F 4 and 6, to receive bolts 7 havingthu1hb-nuts 8 which take their bearings against the brackets 3. Thesides of the posts and brackets are provided with the L- shaped grooves9.

The connecting means include sliding cleats 10, one for each post, andthese cleats are preferably made of two parallel pieces 11 and 1.2,theouter pieces 11 being provided with transverse grooves 18 to receivethe heads 14. of the bolts 7 and the inside pieces 12 provided withtransverse slots 15 aligned with the grooves 13 so that these cleats maybe moved sidewise in order to adjust them to the grooves 16 in thewindow frames in which the window sashes are movable up and down. Bytightening the nuts 8 on. the bolts 7 these cleats may be clamped to theposts in any given lateral adjustment with relation to the posts. sothat one of the devices equipped with them may be used in windows ofdiiterent widths within the maximum lateral extension of these cleatsbeyond the bottom 1. The inner pieces of.

the cleats are provided with transverse batv tens 17 and 18 to cooperatewith the transverse grooves 5 in the posts 2 to insure parallel motion.The outer pieces 11. of the cleats are longer at both endsthan the innerpieces 12 so as to overlap the edge of the bottom 1 at the bottom and tooverlap at the top the cover hereinafter described. The pieces 11 and 12may be united in any suit-' able way so as to make them practicallysolid and we have herein shown them united by means of screw bolts 19,Fig. 4, engag ing the battens 17. a v In eur scheme of a convertibledevice which can be secured in a window without the use of screws ornails. it is. important that the operative parts be consolidated andminimized; In our invention there are no exposed slotsin the cleatadjustment fea= ture's ionl-yOnbolt on each side is necessary; theadjustable eleats are whollyv separate from the cover; there is nostrain .plac edon the cover by the cleats and bolt-s the heads of thebolts are concealed; the bolts may not fall out of place when loosenedor their nuts detached; making the cleats in two parts permits theconcealing" of the bolt heads and the permanent attachment of the boltsand cleats. and the use of the posts to support the cleats and take thestrains admits of a simple and readily operable lateral adjust ment ofthe cleats into and out of the window frame grooves. These and otheradvantages are designedly incident to the construction referred to.

The structure having" the features so far described may be used for avariety of purposes, as for example, as a platform on which a windowwasher or a painter may sit or stand, or it may be arranged so as toproject into the room, as shown in Fig. 2. in order to form a table fora student or other person requiring strong natural light for workingpurposes, but a primary object. of the invention is to utilize thedevice for keeping or protecting food, and for this purpose a cover 20may be used, having a closed end 21, opposite sides 22, and closed top23. A shelf 24 may be proviued also and supported on the sides of thecover, or any number of such shelves may be used.

, The sides 22 of the cover are provided with lugs 25, Figs. 1. 7, 8 and10, which are adapted to enter the grooves 9 by horizontal movement andthen dropped down into the bottom of these grooves to lock the cover onto the posts and over the bottom 1. To provide for the battens 17 and 18the front edges of the sides of the cover are notched at and to providefor the upper ends of the cleats, the cover may be notched as at 27 atboth ends.

A cover such as just described is useful when the device is to beemployed for the keeping of food; but when the device is to be used as ahot-house or for sun-cooking purposes, said cover may be replaced by aglazed cover, such as shown in Fig. 8, and d. ,rnated 28, such a coverbeing made up of suitable wooden or other framing 2:, provided at top,end and sides with panes of glass or other transparent or translucentmaterial 80.

As will he noticed in Figsi and 8, the tops of the covers have anoverhang extending; toward the front, and this for the .purpose of cvering in the cleats and to make as close contact with the glazed windowsash 31 as possible. lVhen the window sash 31 is shut down in front ofthe device, as illustrated in Fig. 1, it serves as a substitute for adoor or other closure for the device, and thus dispenses with thenecessity for a separate closure for the device. l-Vhen the device isplaced on the inside of a room as shown 111mg. 2, the bottoinsash may beraised and t-lietop sash lowered in order to close the window-opening.

lt 11 e listed y ompa i n a es- 1 and 2, that when the device is to beused on the outside, the cleats are arranged in the grooves of the uppersash, while when the device is used inside the room, its cleats arearranged in the grooves of the lower sash.

In addition to the uses described for our invention, it may be addedthat it may afford supports for a board or other platform for workmenengaged in work on the outside of the house, thus serving as a sort ofscaffold platform or as an element of scaffolding.

When the cover is engaged with the grooves 9 in the posts 2 as alreadydescribed, its side and end edges contact with the bottom 1 to make asufficiently tight joint to exclude flies and other insects. and its toprate upon the upper ends of the posts and is in contact with the upperends of the cleats to make similar tight joints at these points. Afterthe cover is in' place and its lugs 25 are settled in the bottoms of thegrooves 9, then the nuts 8 are turned up so as todraw the cleats tightagainst the posts and in proper position in the sash grooves of thewindow if nine, and so the device is held in position in the windowagainst the possibility of accidental dispiz'rcement, and without theuse of screws or nails fastening means. This dispe ing with the use ofscrews, nails or other similar fastening devices avoids marring thewindow frame, and not only so, but provides for the ready portability ofthe device. Obviously the device may be put in position and with equalfacility removed by the proper manipulation of the cleats.

The invention is susceptible of a variety of alterations in structurefrom what has been described, and also in changes in details so long asthe principle of the iuveu tion as herein explained and hereinafterclaimed present.
